In Assassin's Creed Origins, what ancient region is the game's primary setting?

Ptolemaic Egypt is the primary setting of Assassin's Creed Origins.

The game follows Bayek of Siwa during the first century BCE, when Egypt was ruled by the Ptolemaic dynasty. This period combined Egyptian traditions with strong Greek and Hellenistic influence, creating the cultural landscape explored in the game.

The map includes deserts, villages, cities, temples, and the Nile Valley. Alexandria is an especially important urban setting, while the Siwa Oasis is central to Bayek's personal story. Historical figures such as Cleopatra and Julius Caesar also appear in the narrative.

Origins is set before the formal historical development of the Assassin Brotherhood shown in later games. Its story presents the formation of the Hidden Ones, the organization that later becomes associated with the Assassin tradition.
